I am getting the same message. Any resolve?? We do not use Exchange Server in
our office, and this is the only way to keep updated for us. Any resolution
would be appreciated.

I get the same message. First sharing that I did was fine, but now I get
messages whenever I want to manually upload the calendar [the upload of
"calendar" failed. the next upload attempt occurs with the next send/receive.
Server returned an error.] and when I tried to add new email addresses for
sharing. HELP!
